| Description | Repotrectinib is a next-generation tyrosine kinase inhibitor (TKI) specifically designed to address resistance in the treatment of non-small cell lung cancer (NSCLC), specifically due to mutations in the ROS1 gene.[A262056] ROS1 mutations are one of the defined oncogenic drives of NSCLC, and the solvent-front mutation ROS1 G2032R is responsible for 50 to 60% of [crizotinib]-resistant cases.[A262056] Repotrectinib possesses a compact macrocyclic structure that both limits adverse interactions with resistance mutation hotspots and targets mutations in the solvent-front region.[A262061] Although resistance to multiple TKI has been reported, including [crizotinib], [lorlatinib], [taletrectinib], and [entrectinib], there has been no reported case of repotrectinib resistance.[A262066] On November 15th, 2023, the FDA approved repotrectinib under the brand name Augtyro for the treatment of locally advanced or metastatic ROS1-Positive NSCLC. This approval is based on favorable results from the TRIDENT-1 study, where the objective response rate was 79% in TKI-naive patients and 38% in TKI-pretreated patients respectively.[L48741] |
